It was a two-week-long period of research that culminated into me opting for the Casio PX-S6000. It packs all the features needed for home or performing settings into an impressively slim and slick body. The sound is astounding. The keys give off a near-acoustic-piano feel. The screen makes it very easy to navigate through different sounds and settings. There isn't anything not to love about it!
The instrument all in all is extremely sturdy and is of excellent quality. It comes in solid packaging and everything is meticulously wrapped and protected during the delivery process.
Although the year's Casio flagship, the PX-S7000, packs in the €2,222 bill: the keyboard's stand (+awesome cover), pedals, and the 3-colour range, it's still a good idea to opt for the PX-S6000 (€2,072 for all of the above, sans the colours). That will only omit the 52 sounds (albeit including the two grand piano sounds that might be a must-have for professional musicians I guess) and the glamorous pedals with the cute metal handles; but it will gain you the 2 customizable knobs that everyone is going crazy about. And €150!
With its stand and everything, this keyboard is an excellent addition to any home. It's very much worth the money. Getting a standard XX stand is of course an option, and even though the Casio CS-90P stand is a bit overpriced, an XX stand might in fact be too frail for this (fairly large) piano. If it can stand its weight, I doubt it will provide the same stability while playing. Putting it over a stable piece of furniture you already have would be very convenient in this case.
PS. The Thomann staff are always very helpful and will answer any questions you may have!
